我有一个 Spring (3.2.2) 后端为 jQuery Mobile 前端提供静态资源。资源位于地图 /webapp/resources/images 下。此地图中已存在的资源已正确返回，但是当我添加新资源并尝试访问它（使用浏览器）时，我得到 404 not found。当我从地图中删除现有资源时，仍然可以根据请求找到它。我猜这是一些缓存问题？

*更新：*

每次资源更新后，我都会重新加载（停止/启动）在 Eclipse Juno SR2 中运行的 apache-tomcat-7.0.32。还尝试关闭eclipse并重新启动，但没有任何运气。

让我猜猜……您是在应用程序启动后src/main/resources/修改目录的内容吗？源文件夹中的更改对正在运行的应用程序不可见，因为它使用. 文件夹甚至不在类路径上。您可以通过在目录中重复您的步骤来测试这个理论。target/classes/src/target/

如果这不是您的问题的原因，添加有关您的构建工具（Maven？）和 servlet 容器（Tomcat？Jetty？独立？嵌入式？）的信息会有所帮助。

它现在正在工作。@kryger 指出了我的问题（tomcat 发布而不是 resourceHttpRequestHandler）。我打开了服务器选项卡，显示项目已同步。我在 /image 映射中添加了一个资源，仍然是同步的。我注意到对第二个战争项目（用于 web 服务）的引用，该项目目前未使用，因此我删除了此引用。现在，当我添加、修改或删除资源时，它正在重新发布，甚至无需重新启动服务器。
